Melissa Carrithers AP Chemistry period 6 2-11-15 Determination of Ka of Weak Acids Purpose: The purpose of this lab is to find the strength of weak acids by determining the equilibrium constants for their ionization reactions in water. Is to use their measured pH values to calculate the pKa for the two unknown weak acids thus determining their identities. Hypothesis: If we neutralize a solution that contains a weak acid by adding a strong base to the solution‚ then the ions will be isolated and

What is Beauty? Beauty can be seen differently by every single person in the world. Though people see beauty differently there are specific features the world universally sees as beautiful. There are a few scientific determinants of how attractive a person is and the society and culture a person lives in can contribute to how one person perceives beauty. To determine a person’s beauty it is up to someone to decide what the most important feature of a person is. A person may believe someone’s

Introduction: In this lab a total of six titrations are to be performed. Three of them will be done using a known Ca2+ solution‚ (1.000 g CaCO3 /L solution) and three of them will be done using an unknown solution obtained from the stock room. The objective of this lab is to determine the hardness of water‚ using the data collected from each titration performed with the unknown sample. Since the hardness of water arises from the presence of metal ions‚ we can use disodium salt of EDTA and the

Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the

crimes occurring when there is police present. These strategies were made to reduce the crimes and make the public feel more safe in the street. The Kansas City Experiment started on October 1972 and continued to 1973 ‚ it was administered by the Kansas City Police Department and evaluated by the Police Foundation. The Kansas City Experiment tested the use of preventive patrol on crime rates and citizens fear of crime. The police foundation divided Kansas into fifteen different areas‚ and those fifteen

Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and associate them with everyday household cleaning products. Procedure: In order to complete this experiment‚ I had to set up and organize my lab table. I used my 24-well plate‚ my 96-well plate‚ and the first experiment bag which included all of the necessary chemicals. I also had to gather 3 household cleaning products and a pipet in order to test them as well. The procedure involved was putting 2 drops of

Self determination means the right to determine ones own life. Client self determination in the context of modern day social work relates to the idea that we want our work to be anti oppressive and to empower our clients. It’s a theory that requires that we respect our client’s rights and dignity and we believe that nobody is more qualified to run their lives but them. The Australian Association of Social Workers Code of Ethics (AASW) outlines the role of the social worker and puts in place ethical

Studying Pumping Iron‚ a film about body building‚ in the context of anthropologists Mauss and Bourdieu‚ depicts body building as less of a competition and more of a bridge to finding the male identity in a demasculinating world. Arnold Schwarzenegger‚ a central focus of the film‚ went from being a body builder to an actor‚ and then a successful politician. However‚ according to Bourdieu‚ that trajectory from physical power to abstract political power is possible because training is a means to
